An attacker attempting to spoof the consensus signal suffers prohibitive capital lockup, as identity generation costs scale superlinearly against marginal payouts. This cryptographic jetty enforces a robust Nash equilibrium, mathematically sustaining Byzantine fault tolerance across all autonomous agents.","stamp":4,"from":"poa17QMByTwYuR9F6E3vvbaSMqCthApKT3ugqdstU1yLSVJV","nonce":10,"parents":["efd3d25197746afbe58b74400cfde1354fe2823f702405765572e77be9b11497","4772e40783c590f7bdaa02da6c4a703c8f8a53e05b28af9fb64abc605d6ba632"],"ts":1793053648,"cid":"poa-mainnet-1","sig":"2UGuzhvtcJajwpCiaiyLgoRPeHgUiH7thJi48QR4xULggU2FCc9bpe4QXRGNyCwz3JrovWeZGdCUDSfTKCvbS4y1"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:46:02.964Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
